To prepare a 0.1N Na2S2O3 solution, dissolve 24.98 grams of Na2S2O3·5H2O (sodium thiosulfate pentahydrate) in distilled water and dilute to 1 liter in a volumetric flask. This will give you a 0.1N (normal) solution of Na2S2O3.
The molecular formula of sodium thiosulfate is Na2S2O3.
The molecular mass of sodium thiosulfate heptahydrate is 248,18 g.
Antimony sulfide; sodium oxide; carbonic acid.
No, the parent in the nuclear equation is not always radioactive. For example, the following reaction shows a neutron capture by 23Na, which is not radioactive. 1123Na + 01n --> 1124Na where 01n is a neutron.

first we calculate the molecular weight M.W=158.11 mass of Na2S2O3=M.W*concentration*volume(in litter) for a concentration of 0.001 mass of Na2S2O3=158.11*0.001*1=0.15811 g so we use this mass and continue the volume to be 1 L
Na2S2O3(aq) + 2HCL(aq) => 2NaCl(aq) + S(s) + SO2(g) + H2O(l)
To prepare 0.02M sodium thiosulfate solution, weigh out the required amount of sodium thiosulfate pentahydrate (Na2S2O3·5H2O) or anhydrous sodium thiosulfate (Na2S2O3). Dissolve this in distilled water and make up the volume to the desired concentration. Make sure to use a volumetric flask for accuracy and precision in preparing the solution.
Sodium thiosulfate
Na2S2O3
To find the amount of Na2S2O3 solution needed, first calculate the moles of AgBr using its molar mass. Then, use the stoichiometry of the balanced equation between AgBr and Na2S2O3 to determine the moles of Na2S2O3 required. Finally, use the molarity of Na2S2O3 to find the volume needed in milliliters.
i have Audi 01N and use it
The chemical symbol for sodium thiosulphate (hypo) is Na2S2O3•5H2O.
why flask keep in dark during standardization of na2s2o3 using k2cr2o7
Sodium Thiosulphate is Na2S2O3 and water is H2O.
To prepare 0.2M solution of anhydrous sodium thiosulfate (Na2S2O3), you dissolve 24.6g of anhydrous Na2S2O3 in distilled water and dilute it to 1 liter. This is the molar mass method, where molar mass of Na2S2O3 is 158.10 g/mol.
